LoRaWAN Wireless Fridge & Freezer Monitoring Sensor with Internal & External Pro

The LoRaWAN Fridge Monitoring Sensor is purpose-built for pharmacies, hospitals, food safety, and laboratories that require precise, reliable cold storage monitoring. It combines a built-in temperature sensor for ambient cabinet monitoring with an external probe for accurate fridge and freezer readings.

With long-range LoRaWAN connectivity, the device transmits real-time temperature data securely to your monitoring platform. The built-in data logging function ensures no readings are lost, even during temporary network outages. Remote configuration and firmware upgrades make it flexible and future-proof.

Powered by a 2400mAh battery with up to 10 years of life, this compact sensor provides long-term peace of mind while reducing maintenance. It’s ideal for ensuring compliance with HACCP, GSP, GDP, and vaccine cold chain requirements.
